3D rotation matrices are used to rotate objects in three-dimensional space around one of the principal axes: X, Y, or Z. Each matrix defines how the coordinates of a point change when it is rotated by a certain angle around a specific axis. These matrices are fundamental in fields like computer graphics, robotics, and aerospace engineering, where precise control of orientation and movement is essential. 📌Support us - Like/Share/Follow👆❤️ ✅Follow @math.magazine 🔥 for more !!... ✅Follow @manim.
